Following a wave of thunderstorms that prompted a tornado warning across the Southside, the weather has mostly recovered to just a few scattered showers.

Traffic is another story.

Most metro interstates are in stop-and-go mode as the evening commute begins ramping up, according to the WSB 24-hour Traffic Center.

All lanes of Ga. 400 South were blocked near Windward Parkway because of a crash, but Alpharetta police said all lanes reopened just after 4:15 p.m. Traffic still remains slow in the area, and the Traffic Center recommends taking Ga. 9 as an alternate.

Three eastbound lanes of I-20 are also blocked by a crash near Candler Road, the Traffic Center reported. Flat Shoals Road is recommended as an alternate.

On the bright side, conditions on I-75 in Henry County have vastly improved after a fallen tree was removed from a right lane of the interstate, according to the Traffic Center.

The prior tornado warning included parts of Clayton, DeKalb, Henry and Rockdale counties, and it expired at 2 p.m., according to the National Weather Service. However, some damage has been reported in Lake City and Ellenwood, Channel 2 Action News meteorologist Brad Nitz said. Wind gusts reached 40 to 50 mph.

The power was out at Locust Grove city hall, and several trees and downed power lines were reported, the city posted on Facebook. More than 17,000 outages continue across the state as of 4:50 p.m., according to Georgia Power.

A tree also fell on top of a home in Forest Park, Channel 2 meteorologist Eboni Deon reported.

Some lighter rain lingers in Atlanta as the heavier storms move to the southeast corner of the state, Channel 2 reported.

This all comes after a foggy morning, which blanketed metro Atlanta during the morning rush hour. Visibility dropped to near zero at times until the dense fog advisory expired at 10 a.m.

That was all thanks to a cold front that is sliding through the state, according to Channel 2 meteorologist Brian Monahan.

The storms cooled Atlanta considerably. The city reached the upper 60s around noon and dropped nearly 10 degrees by 3:15 p.m. As night falls, temperatures will drop back into the 30s by Wednesday morning.
